    Jay,

    I remember reading about aircraft radial motors from the 40’s. No pistons were available so they took the cylinders & had them plated in the bore, then rebored to fit the old pistons matching pistons to each cylinder to complete the refirbish. The engines, Pratt & Whitney motors 1200hp passed FAA inspections & now in the air again. Another possabilty maybe?

    Have you had any luck on E Bay?
